Edit: The file transfer did stop. It stalled and didn't report any errors so I thought it was fine, but it did stop transferring. Thanks for the bug report! Looks like it might be related to bug 245653 and bug 243985. I get a very similar backtrace in current trunk (see below) if I do the following (see bug 245878 comment 1): 1. Open Dolphin (I've set it to remember view properties for all folders). 2. Switch to Icons View (if it's not already in that view mode). 3. Open a subfolder of ~. 4. Switch to Columns View. 5. Open a subfolder of the folder which is open in the view. 6. Switch back to Icons View. 7. Go "Back". It seems that DolphinView's m_selectionModel became a dangling pointer (because the column's selection model has been deleted) which leads to a crash when trying to disconnect its signal. It might help to make it a QPointer or another type of smart pointer. #6 0x00007f20c6a8ce0b in QObject::disconnect (sender=0x8a5e00, signal=0x88a4b9 "selectionChanged(QItemSelection,QItemSelection)", receiver=0xa0fff0, method= 0xa8c109 "slotSelectionChanged(QItemSelection,QItemSelection)") at kernel/qobject.cpp:2722 #7 0x00007f20ca4aa325 in DolphinView::setUrl (this=0xa0fff0, url=...) at /home/kde-devel/kde/src/KDE/kdebase/apps/dolphin/src/views/dolphinview.cpp:562 #8 0x00007f20ca9a7a1d in DolphinViewContainer::slotUrlNavigatorLocationChanged (this=0x7a8f60, url=...) at /home/kde-devel/kde/src/KDE/kdebase/apps/dolphin/src/dolphinviewcontainer.cpp:440 #9 0x00007f20ca9a8745 in DolphinViewContainer::qt_metacall (this=0x7a8f60, _c=QMetaObject::InvokeMetaMethod, _id=19, _a=0x7fff25f28270) at /home/kde-devel/kde/build/KDE/kdebase/apps/dolphin/src/dolphinviewcontainer.moc:139 #10 0x00007f20c6a7992b in QMetaObject::metacall (object=0x7a8f60, cl=QMetaObject::InvokeMetaMethod, idx=46, argv=0x7fff25f28270) at kernel/qmetaobject.cpp:237 #11 0x00007f20c6a8e73d in QMetaObject::activate (sender=0x91c790, m=0x7f20ca220620, local_signal_index=1, argv=0x7fff25f28270) at kernel/qobject.cpp:3272 #12 0x00007f20c9fefd05 in KUrlNavigator::urlChanged (this=0x91c790, _t1=...) at /home/kde-devel/kde/build/KDE/kdelibs/kfile/kurlnavigator.moc:160 #13 0x00007f20c9fee3d9 in KUrlNavigator::goBack (this=0x91c790) at /home/kde-devel/kde/src/KDE/kdelibs/kfile/kurlnavigator.cpp:842 #14 0x00007f20ca99a0af in DolphinMainWindow::goBack (this=0x763a60) at /home/kde-devel/kde/src/KDE/kdebase/apps/dolphin/src/dolphinmainwindow.cpp:832 Created attachment 50728 [details] Use a QPointer for DolphinView's m_selectionModel member This patch fixes it for me.

Application: dolphin (1.5) KDE Platform Version: 4.5.00 (KDE 4.5.0) Qt Version: 4.7.0 Operating System: Linux 2.6.32-24-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I started a transfer from an external hard drive to my local disk ~5 minutes before the crash. When the crash occured, I had 2 Dolphin windows open. The transfer was unaffected by the crash. The crash does not seem to be reproducible. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [Current thread is 1 (Thread 0x7f71c0789760 (LWP 1778))] Thread 2 (Thread 0x7f71ab4a7710 (LWP 1781)): #0 0x00007f71c005ff83 in *__GI___poll (fds=<value optimized out>, nfds=<value optimized out>, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007f71b7be84a9 in ??
